Tool grinding machine MHK6025 series

workpieceCNC4-axis

Product overview
The CNC tool grinding machine adopts a Siemens 828DBASIC four-axis CNC control system and AC servo unit drive, enabling four-axis, four-linkage operation:

• Longitudinal movement of the worktable
• Transverse movement of the grinding head
• Vertical movement of the grinding head
• Rotary movement of the CNC indexing head
